+This directory contains the USB Tranzport Kernel driver for Linux.
+
+At present it accepts reads/writes of 8 byte cmds to /dev/tranzport0 to control
+the lights and screen.
+
+Reads are possible. Wheel Compression does not currently account for button changes
+
+It also has some sysfs hooks that are non-functional at the moment.
+
+The API is closely tied to the ardour revision and WILL change. 
+
+A sysfs interface is PERFECT for simple userspace apps to do fun things with the
+lights and screen. It's fairly lousy for handling input events and very lousy
+for watching the state of the shuttle wheel.
+
+In the end this is going to be driven by a midi layer

+<H3>Footswitch</H3>
+
+At least on every footswitch I've tried, the polarity appears to be wrong, in that the footswitch "up" position results
+in 0100 being OR'd into the result. Pressing it down results in a 0, if no other keys are pressed. Releasing it results in 0100.
+
+Every other key when up results in 0. This odd behavior would hopefully be controllable via a command to the tranzport,
+but I don't have that, so dealing with footswitch events is weird. 
+
+So, seeing this bit enabled would be something like "HAVE_FOOTSWITCH INSTALLED", BE SMART ABOUT IT.
+
+
+<H3>Special Key Combinations</H3>
+<p>
+In addition to the normal keycodes generated by the tranzport, it is possible to hit several combinations of keys and get a unique
+result. Some are really weird. Perhaps the following assignments make sense:

+tranzport 0.1 <tranzport.sf.net>
+oct 18, 2005
+arthur@artcmusic.com
+---
+
+The Frontier Design Tranzport(tm) (www.frontierdesign.com) is a simple
+wireless USB device. It is not a MIDI device. The document on their web
+site "Tranzport(tm) Native Mode Interface Description" describes the
+Tranzport(tm) as if it were a MIDI device, but this is implemented by their
+Windows and Macintosh software drivers.
+
+This code will allow you to use your Tranzport(tm) at a lower level of
+abstraction. This code relies on libusb, which can be obtained from
+libusb.sourceforge.net.
+
+To compile the program, type "make". You should end up with a executable
+called "tranzport". You'll probably have to run this program as root.
+
+Using the program is straightforward. It will simply tell you which
+buttons are being pressed and what not. If you press one of the buttons
+with a light, the light will turn on. If you hold shift and press one of
+the buttons with a light, the light will turn off. If you take out the
+batteries to the device (or go out of range), it will tell you that the
+device is offline. When you replace the batteries (or come back in
+range), it should tell you it is back online.
+
+Once you understand how everything works, you should be able to
+incorporate it into your own setup however you wish.
+
+This code was developed on a Linux machine, but (theoretically) it
+should work on any system that is supported by libusb, since that is how
+it communicates with the device.
+
+Here are a few more details about the device:
+
+There are two endpoints for communication with the device. All data
+reads and writes are done in 8-byte segments.
+
+One endpoint is for interrupt reads. This is used to read button data 
+from the device. It also supplies status information for when the device 
+goes out of range and comes back in range, loses power and regains 
+power, etc. The format of the data is:
+
+    00 ss bb bb bb bb dd 00  (hexadecimal)
+
+where:
+
+    ss - status code, 01=online ff=offline
+    bb - button bits
+    dd - data wheel, 01-3f=forward 41-7f=backward
+
+Please refer to the source code for a list of the button bits.
+
+The other endpoint is for interrupt writes. This is used to toggle the
+lights on the device, and to write data to the LCD.
+
+There are 7 lights on the device. To turn a light on, send the following 
+sequence of bytes:
+
+    00 00 nn 01 00 00 00 00  (hexadecimal)
+
+where nn is the light number.
+
+To turn a light off:
+
+    00 00 nn 00 00 00 00 00  (hexadecimal)
+
+Here is the list of lights:
+
+    00  Record
+    01  Track Rec
+    02  Track Mute
+    03  Track Solo
+    04  Any Solo
+    05  Loop
+    06  Punch
+
+The size of the LCD is 20x2, and it is split into 10 cells, each cell
+being 4 characters wide. The cells progress across, then down. To write
+to the LCD, send the following sequence of bytes:
+
+    00 01 cc aa aa aa aa 00  (hexadecimal)
+
+where:
+
+    cc - cell number
+    aa - ASCII code
+
+Here is a list of the cells to clarify:
+
+    00  row 0, column 0-3
+    01  row 0, column 4-7
+    02  row 0, column 8-11
+    03  row 0, column 12-15
+    04  row 0, column 16-19
+    05  row 1, column 0-3
+    06  row 1, column 4-7
+    07  row 1, column 8-11
+    08  row 1, column 12-15
+    09  row 1, column 16-19
+
+You should refer to the "Tranzport(tm) Native Mode Interface
+Description" document for a listing of the ASCII codes the LCD uses.

+tranzport 0.1 <tranzport.sf.net>
+oct 18, 2005
+arthur@artcmusic.com
+---
+
+The Frontier Design Tranzport(tm) (www.frontierdesign.com) is a simple
+wireless USB device. It is not a MIDI device. The document on their web
+site "Tranzport(tm) Native Mode Interface Description" describes the
+Tranzport(tm) as if it were a MIDI device, but this is implemented by their
+Windows and Macintosh software drivers.
+
+This code will allow you to use your Tranzport(tm) at a lower level of
+abstraction. This code relies on libusb, which can be obtained from
+libusb.sourceforge.net.
+
+To compile the program, type "make". You should end up with a executable
+called "tranzport". You'll probably have to run this program as root.
+
+Using the program is straightforward. It will simply tell you which
+buttons are being pressed and what not. If you press one of the buttons
+with a light, the light will turn on. If you hold shift and press one of
+the buttons with a light, the light will turn off. If you take out the
+batteries to the device (or go out of range), it will tell you that the
+device is offline. When you replace the batteries (or come back in
+range), it should tell you it is back online.
+
+Once you understand how everything works, you should be able to
+incorporate it into your own setup however you wish.
+
+This code was developed on a Linux machine, but (theoretically) it
+should work on any system that is supported by libusb, since that is how
+it communicates with the device.
+
+Here are a few more details about the device:
+
+There are two endpoints for communication with the device. All data
+reads and writes are done in 8-byte segments.
+
+One endpoint is for interrupt reads. This is used to read button data 
+from the device. It also supplies status information for when the device 
+goes out of range and comes back in range, loses power and regains 
+power, etc. The format of the data is:
+
+    00 ss bb bb bb bb dd 00  (hexadecimal)
+
+where:
+
+    ss - status code, 01=online ff=offline
+    bb - button bits
+    dd - data wheel, 01-3f=forward 41-7f=backward
+
+Please refer to the source code for a list of the button bits.
+
+The other endpoint is for interrupt writes. This is used to toggle the
+lights on the device, and to write data to the LCD.
+
+There are 7 lights on the device. To turn a light on, send the following 
+sequence of bytes:
+
+    00 00 nn 01 00 00 00 00  (hexadecimal)
+
+where nn is the light number.
+
+To turn a light off:
+
+    00 00 nn 00 00 00 00 00  (hexadecimal)
+
+Here is the list of lights:
+
+    00  Record
+    01  Track Rec
+    02  Track Mute
+    03  Track Solo
+    04  Any Solo
+    05  Loop
+    06  Punch
+
+The size of the LCD is 20x2, and it is split into 10 cells, each cell
+being 4 characters wide. The cells progress across, then down. To write
+to the LCD, send the following sequence of bytes:
+
+    00 01 cc aa aa aa aa 00  (hexadecimal)
+
+where:
+
+    cc - cell number
+    aa - ASCII code
+
+Here is a list of the cells to clarify:
+
+    00  row 0, column 0-3
+    01  row 0, column 4-7
+    02  row 0, column 8-11
+    03  row 0, column 12-15
+    04  row 0, column 16-19
+    05  row 1, column 0-3
+    06  row 1, column 4-7
+    07  row 1, column 8-11
+    08  row 1, column 12-15
+    09  row 1, column 16-19
+
+You should refer to the "Tranzport(tm) Native Mode Interface
+Description" document for a listing of the ASCII codes the LCD uses.

+	This handles the plugin duties, and the midi encoding and decoding,

+
+	The model of the control surface is handled by classes in controls.h
+
+	What happens is that each strip on the control surface has
+	a corresponding route in ControlProtocol::route_table. When
+	an incoming midi message is signaled, the correct route
+	is looked up, and the relevant changes made to it.
+
+	For each route currently in route_table, there's a RouteSignal object
+	which encapsulates the signals that indicate that there are changes
+	to be sent to the surface. The signals are handled by this class.
+
+	Calls to signal handlers pass a Route object which is used to look
+	up the relevant Strip in Surface. Then the state is retrieved from
+	the Route and encoded as the correct midi message.

+
+I'm putting this here because I don't really have a place to put it, unless I create a web page and have a place to keep the code.
+
+While doing some exaustive testing of my latest code (read - playing a ton of music) I have done some thinking about the ui, and decided that under apparent simplicity should lie complexity.
+
+The "flash" screen idea I am going to drop, and replace it with the idea of a notify area being declared on each screen.
+
+When the unit is idle, these messages will appear in that area statically. When the transport is running, these messages will still appear in that space, which is usually where the meter is. It's actually possible to rapidly flash the area between the competing writers and get a nifty faded effect. (I came across this idea accidentally when I had a pointer overrun)
+
+Also certain things will update on top of each other, whatever was updated 
+last will stay on the screen. This is Pan/Gain primarily.
+
+I need a way to get messages back into the tranzport. Example - I hit Undo, what was undone? Redo, same problem.
+
+I've already found many uses for being able to control more than 1 track at a time, so I think that although I'm *usually* controlling one track at a time, being able to quickly access all tracks would be good.
+
+Example - want to have meters for all tracks running and be able to control the
+db/pan settings of the track I'm on....
+
+What I am going to go with is multifold - but first my design goal: I want to do everything required for a solo musician wielding an instrument to NOT have to touch a keyboard or look at a big screen. When you are wrapped behind a bass, it's difficult to cope with that - but the tranzport is a great alternative.
+
+Most screens will have *4* items on them.
+
+There will be "display views" - which are more informational and bling oriented.
+
+There will be "Track based views"- which basically do track specific things
+
+There will be "interactive views",which basically allow for more input than output. They will do something to highlight the current selection.
+Scroll wheel will select between values for a field. Track Next/Prev will move between fields. I would like to have a "No/Yes" option (hit record for yes? Stop for no?) but I'm still a little vague on that.
+
+Things to do:
+
+A) Hitting "Shift->Spacebar" will switch "views". There are ultimately going to be dozens of views. At present, there are only the "Normal" and "Big Meter" views.
+
+Each view will change somewhat based on the state of the transport. Holding down shift for a second will switch to the "underlying display"....
+
+Here's how the "normal" view looks today in my tree:
+
+VIEW: NORMAL
+
+Play Mode: Stopped
+[Trackname[16]] [gain/pan[4]]
+[Modes[9]] long smpte/bar counter]
+
+Play Mode: Playing > 1.0 speed
+[Trackname[16]] [gain/pan[4]]
+[meter[16]] short smpte/bar counter]
+
+Play Mode: Playing < 1.0
+[Trackname[16]] [gain/pan[4]]
+[meter[9]] long smpte/bar counter]
+
+Play Mode: Recording
+[Trackname[16]] [gain/pan[4]]
+[meter[16]] short smpte/bar counter]
+
+Other views (in order of development priority)
+
+Marker Mode: Edit markers, setup loops and punch in points.
+Config Mode: Load/Save settings, Load/Save project. Set wheel SnapTo
+Loop Mode: Show track, raise layers to top for playback, editing, deletion, loop on and off, etc
+
+It's possible that config mode will have a "MORE" field, or ways to move around the configuration (ffw/Play?)
+
+(the first two are the two modes I most need personally. If you have a suggestion...)
+
+Mastering Mode - display master and current track with meters and panner/db
+Automation Mode - I really don't think I have the pixels for this
+
+(I've already abstracted out the code to do most of these, but it's bling, I'm not going to bother much with it soon)
+
+Quad Meter Mode
+Inverted Meter mode (draws meters backwards)
+Quad Inverted Meter mode (bling, but my car stereo has it, and it's cool)
+10 8 bar meter mode
+5 8 bar meter mode
+
+I haven't written the panner yet, doing the stereo meter killed me.
+
+From a development perspective I'm going to keep revising the code to make it more stable and merely tie the new mode modes to the "bling mode"s until they are ready for prime time. I should be able to put out releases once a week for a while.
+
+A big help would be moving these items into a higher level of abstraction (revising the baseUI class).
+
+In particular, I'd really like "slave" mode. Snapto increment is really important....
+
+Here's an example of something that should be fairly easy to export to the Base::UI subclasses - the current state of the main keyboard's shift key.
+
+That way, when shift is held down for a few seconds on the regular keyboard, I can see what's underneath the current tranzport display mode (I do like big meters) (Also, it's somewhat easier to hit shift on the main keyboard and play on the tranzport or the shuttle wheel, if that's what you are doing).
+
+Should be fairly easy to tap into the gdk event for this but the "right way" to propagate this event into the class is beyond me.

+
+/* Design notes: The tranzport is a unique device, basically a 
+   20x2 character lcd gui with (almost) 22 shift keys and 8 blinking lights. 
+
+   As such it has several unique constraints. In the libusb driver,
+   the device exerts flow control
+   by having a usb write fail. It is pointless to retry madly at that point,
+   the device is busy, and it's not going to become unbusy very quickly. 
+
+   So writes need to be either "mandatory" or "unreliable", and therein 
+   lies the rub, as the kernel can also drop writes, and missing an
+   interrupt in userspace is also generally bad. 
+
+   However, the kernel driver retries writes for you and also buffers and 
+   compresses incoming wheel events - it will rarely, if ever, drop data.
+
+   A more complex surface might have hundreds of lights and several displays.
